I have a split rar archive, with like 20 parts. Well one part says CRC failed, the file is corrupt. But I know it isn't a bad file, becuase many other people have downloaded the same one, with no problems extracting it. This isn't the first time this has happened lately either, it seems it's becoming repetitive lately. I just upgraded to the latest winrar also, so that's no problem.

EDIT now it's like every odd number file that's having that problem, and other files are having different CRC errors.
